7-Zip also has small footprint and uses less resources as POCO ZIP . POCO ZIP on the other hand does have a nice interface.7-ZIP does have an edge on all the others I have tried with compression rates.

However , Thanks to everyone that has replied . Winrar was considered but ruled it out because is slightly slower , takes too much resources but the interface was nice looking.

I am stuck with "Just ZipIt" can only zip & unzip zip files using Deflate64 for lrge files and I am currently thinking about "Zip Genius" also free but 5.98MB , bit large for a Compression Program........Bloat...........Thanks for the post though...
